Karakteristik Material Sandfill dari Berbagai Quarry terhadap Rasio Pemadatan dan Daya Dukung Tanah pada Pekerjaan Reklamasi Pelabuhan Patimban Paket 6

Reclamation is a strategic method for providing new land, particularly for the development of port infrastructure, and is highly dependent on the quality of sandfill materials and the achieved level of compaction. In the Patimban Port Reclamation Project Package 6, sand materials were sourced from several quarries with varying physical characteristics, which may influence the compaction ratio and soil bearing capacity. This study aims to analyze the characteristics of sandfill materials obtained from four different quarries and to evaluate their performance in terms of compaction and soil bearing capacity. A quantitative approach with a comparative research design was adopted, involving laboratory and field tests, including particle size distribution, clay content, specific gravity, modified proctor, sand cone test, and field California Bearing Ratio (CBR) testing using a mechanical jack. The results indicate that all materials comply with the project technical specifications, achieving field compaction ratios exceeding 95% and CBR values significantly higher than the minimum requirement of 6% in accordance with applicable standards. Variations in gradation characteristics and clay content affect the maximum dry density and bearing capacity, overall, all sandfill materials are considered suitable for use in the Patimban Port Reclamation Project Package 6
